What better way to learn all about buoyancy and Archimedes’ principle than with the Jellyfish Cartesian Diver! Fun and educational, you can perform three different experiments with the Jellyfish Cartesian Diver.
Sink Quick Experiment: Squeeze the bottle hard and the Jellyfish Cartesian Diver will sink quickly. The Jellyfish will float up when you let go of the bottle.
360 Rotation Experiment: When the Jellyfish Cartesian Diver is moving up, keep squeezing and letting go of the bottle over and over again, then the Jellyfish will rotate while moving up.
Keep Still in Water Experiment: Adjust your holding pressure to keep the Jellyfish Cartesian Diver still in the water.
The Jellyfish Cartesian Diver comes in three different assorted colours; red, blue and orange.
